Factual error: The ferry splits in half down the middle, enough so the water is flooding in dramatically as the split grows. There is no possible way that the two halves of the ferry could have remained afloat like that. It would have sunk immediately. Then, as Iron Man "welds" the two halves back together, the ferry is afloat at the same waterline as before the incident, certainly not feasible with all the water it took on.
Suggested correction: You're forgetting all the cars that the ferry lost. This would even out the weight to roughly what it was before.
Other mistake: A poster in the school states that the Academic Decathlon takes place on October 14-15. But later on in the movie, another poster says it's on September 14.
Suggested correction: Was in a similar thing in HS. Not too surprisingly, we had more than one event throughout the year. In fact, I've never heard of an extra-curricular with only 1 event. Likely 2 different meets.
They said later on, though, and that would go into the next school year, which is weird for most extracurriculars to have pre-planned events for the next school year.
Trivia: Adrian Toomes is never referred to as "The Vulture" in the movie.
Suggested correction: Not exactly true. After Spider-Man defeats Toomes at Coney Island and leaves him tied up for the authorities, the note he leaves that Happy reads refers to him as the "Flying Vulture Guy."
